It's fixed in 0.3 anyway, so it won't affect client (like crash) with any invalid things, so IsValidSkin is not needed really.

pawn Код:

zcmd(setskin,playerid,params[])
{
  new targetid,skin;
  if(sscanf(params,"ud",targetid,skin)) SendClientMessage(playerid,WHITE,"/setskin [playerid] [skinid]");
  else if(targetid == INVALID_PLAYER_ID) SendClientMessage(playerid,RED,"Invalid player id");
  else if(!IsValidSkin(skin)) SendClientMessage(playerid,RED,"Invalid skin id");
  else
  {
    SetPlayerSkin(targetid,skin);
  }
}

And Jake if you are asking what to do with this, you should really read some turtorials before comming back and asking again.
